Which astrophysical law decides DISTANCE (d) and DENSITY (D) factors of nine planets of the Solar System?
(1) Why planet Pluto located at farthest distance (5900 Million Klm) from the Sun while planet Mercury located in the nearest orbit (57.9 Million Klm)?
(2) Why DENSITY of the Earth is (1.00) greater than planet Uranus (0.23)? Is there any Law exist which decides DISTANCE & DENSITY factors of planets in the Solar System? Or these are just ‘random’ factors? Up today, there is no answer for this problem in Astrophysics, but now with efforts of 20 years, I have discovered the natural LAW, which is followed by nine planets. This is DENSITY-DISTANCE LAW (DdL). This law is the part of STREPULSION PHYSICS.

DdL: DENSITY (D) and DISTANCE (d) are mutually interlinked reverse factors. That is to say, as D increases d decreases.
THE LAW: (1) i.e., (2)
(1) DENSITY IS INVERSELY PROPORTIONAL TO SQUARE ROOT OF DISTANCE:
(2) DISTANCE IS INVERSELY PROPORTIONAL TO SQUARE OF DENSITY

As DISTANCE is known factor, let us compute DENSITIES of nine planets on basis of above LAW 1:
d = DISTANCE between the Planet and the Sun in unit of Million Kilometres.
D = DENSITY when Earth Density = 1.

Follow the Table/calculations on next page.

TABLE 1: LAW: : C = Constant = 12.231 = root of Earth d.

PLANETS	DISTANCE : d = l/D2	:	= DENSITY:	OLD & WRONG VALUES OF DENSITY:
MERCURY	: 57.9	: 12.231/7.609	= 1.607	: 1.00
VENUS	: 108.2	: 12.231/10.401	= 1.175	: 0.96
EARTH	: 149.6	: 12.231/12.231	= 1.000	: 1.00
MARS	: 227.9	: 12.231/15.096	= 0.809	: 0.71
JUPITER	: 778.3	: 12.231/27.898	= 0.438	: 0.24
SATURN	: 1427.0	: 12.231/37.775	= 0.323	: 0.13
URANUS	: 2869.6	: 12.231/53.568	= 0.228	: 0.31
NEPTUNE	: 4496.6	: 12.231/67.056	= 0.182	: 0.33
PLUTO	: 5900.0	: 12.231/76.811	= 0.159	: unknown

COMENTS:
1) Old values of DENSITIES of planets are wrong and should be corrected as above.
2) The LOWEST DENSITY is of the PLUTO, not SATURN.
3) The HIGHEST DENSITY is of the MERCURY, not EARTH.
4) The Higher DENSITY of Mercury Planet than old estimation is accepted by NASA, Washington after tracking mission of the Spacecraft Mariner 10.

So, DISTANCE and DENSITY factors of nine planets are not just random but follow the LAW, which I have stated here. MERCURY Planet is located in nearest orbit to the Sun because it is HIGHEST in DENSITY and PLUTO at farthest because it is LOWEST in DENSITY. Density of the EARTH is greater than URANUS because it is nearer to the Sun than Uranus.
